PRESERVE-JAR AND STOPPER.

SPECIFICATION forming part of Letters Patent No.634,240, dated October 3, 1899. Application filed December 6, 1898. Serial No. 698,430. (No model.)

To all whom, it nuty concern.-

Be it known that I, Lewis S. Horr, a citizen of the United States of America, and a resident of Boston, in the county of Suffolk and State of Massachuset-ts,have invented certain new and useful Improvements in Preserve-Jars and Stoppers, of which the following is a specification.

My invention relates to improved methods of making-jars or bottles to contain preserved condiments and in the applied devices for sealing the same, the purpose being to provide a durable, efficient, and easily adjusted and removable covering which shall lock and hermetically seal, so as to insure the contents of such vessels against impairment. To produce these desirable results, I proceed in the manner hereinafter described, and illustrated in the annexed drawings, forming a part of this specification, wherein- Figure 1 is a longitudinal section, in part, of a jar with my improved covering loosely adjusted within its mouth. Fig. 2 designates a similar view of such a jar with the covering tightly compressed so as to lock and hermetically seal the jars content-s. Fig. 3 is a Vertical transverse section of the stopper. Fig. t exhibits a similar view, showing a round sealing-bod y in the place of the oblong body shown in the previous figure. Fig. 5 is a view of the appurtenances required to compress the covers and expandthe sealing-band,shown in normal and compressed position.

Oorrespondin g letters show similar features throughout the several views, referring -to which A is the jar, having within the inner circum ference of its neck B the annular -shaped recess 0 to receive the elastic sealing-band surrounding the organized cover when the band is under compression and expansion. This constitutes the improvement in the jar. The stopper or cover bodies comprise the, upper portion E, Fig. 3, having outwardly the circumferential acute-angle bearing F, fitting over the orifice of the jar A, and the inwardlycurved exterior body G to receive the secondary body H, forming the lowerportion of the cover, which may be'of any material, though preferably of glass. Said body H is designed to receive the flat or the round sealing-band I, as in Fig. 3, which rests against the lower half of the curved side G of the upper cover portion E and the rim H of the lower body H, thus forming a cushioned barrier between the upper and lowerbodies, the floor of the former portion E being contracted, as at J, while the floor of the latter portion II is extended, as at K,to receive the lower half of the stopper-bod y E, the two bodies E and H being loosely attached by the retaining-rod L,passin g through the floor J. The upper end of the said rod is provided with an eye M. This receives the tongue N of the finger-lever N, which lever operates to close and release the two bodies E and H, forming in their assemblage my improved stopper. at one end of the finger-lever a cam, as at 0, Fig. 5, thus positioned when the bodies E and H are to be drawn together to close the mouth of the jar and in the dotted position when said cover is to be released therefrom. To resist the compressive action of the cam O, the helical spring P is placed about the rod L, whose lower end is firmly united to the base of the lower body H, by being cast into it when the material is in a molten condition.

The finger-lever N when depressed, as in. Fig. 2, draws the lower body II against the upper body E, While the outwardly-interven-. ing elastic sealing-band Lbeing driven against the inner side of the neck of the jar- B, is expanded, so as to compactly fill the annular recess 0 within the mouth of the jar, thus looking and hermetically sealing the contents of the vessel.

In assembling the two sections E and H it is'desirable that the former shall just enter the latter, so as to form a junction, as at- Q, Fig. 4, when the spring P is relaxed to its extreme limit. When, therefore, the operation of the cam 0 draws together the parts E and H, the vertical rim of the latter rides up on the exterior wall of the curved body G, expanding the elastic sealingband I, so as to completely fill the recess 0, as previously described. Upon the release of the spring P this tension is relaxed, when the sealing-band I retracts to its normal position, as in Fig. 3, permitting the cover to be easily withdrawn from the jar.

Having described the nature and construction of my improved in'vention, I desire not to be confined to a close interpretation there- To accomplish this, I form stopper-bod y, the means attached to the retaining-rod to compress the spring to draw the lower stopper against the upper stopper and the elastic sealing-band adapted to be expanded as said stopper-bodies are drawn together substantially in the manner set forth.

Signed by me at Boston, Massachusetts, this 3d day of December, 1898.
